When plugging my Samsung Galaxy Relay phone into a Windows box via<br>
USB, the filesystem comes right up [1] and I can transfer files, etc.<br>
But on my Linux (Debian Sid) ThinkPad I can not access any of the<br>
files on this phone.<br>
<br>
Apparently starting with Android Honeycomb, storage is no longer<br>
accessed as a USB mass-storage drive, but rather exposed via MTP &<br>
PTP. I guess there are advantages to the approach [2], but one major<br>
disadvantage I'm finding is that I cannot access any of the files on<br>
this phone from my Linux laptop:<br>
<br>
% mtpfs -o allow_other /mnt/phone<br>
[...]<br>
Attempting to connect device<br>
PTP_ERROR_IO: failed to open session, trying again after resetting USB interface<br>
LIBMTP libusb: Attempt to reset device<br>
LIBMTP PANIC: failed to open session on second attempt<br>
Unable to open raw device 0<br>
<br>
Looks like a bug in libmtp (& maybe mtpfs) [3] is responsible, but in<br>
searching around for solutions I get the impression that file transfer<br>
between post-Gingerbread Android devices and Linux boxen is generally<br>
marginal. If you've experience otherwise, could you share your success<br>
stories?<br>
<br>
[1] Seems like a security issue to me -- plug phone into computer to<br>
charge it and all the phone's files are automatically exposed to<br>
the computer. Old Android devices required you to explicitly mount<br>
the filesystem, allowing USB charging sans filesystem exposure.<br>
